I'm trying to add layer name using the field-calculator in QGIS (3.4.1). If I do this manualy it works fine, but if I do this using the processing-modeler I get NULL for every field. I just type @layer_name in the Formula field. Field-type is string and length is 50. enter image description here

  • Perhaps a bug in 3.4.1? This seems to work fine in 3.4.0. – Joseph Dec 6 '18 at 13:56
